Abstract
A wireless communication system including a transmitter and a receiver. The transmitter includes a first mixing module, a phase-locked loop module, reference oscillator, and a second mixing module. The first mixing module is configured to combine a low-frequency data signal and an audio signal, and to generate a first combined signal. The phase-locked loop module is configured to generate a phase error signal based on a reference signal and a frequency modulated signal. The reference oscillator generates the reference signal having a frequency based on the low-frequency data signal. The second mixing module is configured to combine the first combined signal and the phase error signal, and to generate a second combined signal. The transmitter generates the frequency modulated signal based on the second combined signal and transmits the frequency modulated signal. The receiver is configured to receive the frequency modulated signal, and extract the low-frequency data signal and the audio signal.
